IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 4t2,2d, dated April, 1864.

To all whom it' may concern:

Be it known that I, CHARLES P. WING, of Fayetteville, in the county of Onondaga and State of New York, have invented certain new and useful Improvements in Harvesters; and I do hereby declare the following to be afull and exact description ofthe same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a plan or top view of my invention. Fig. 2 is a vertical transverse section of the same in the line m. Fig. 3 is a side elevation thereof. FiguiC is asection in thelineyy.

Similar letters of reference indicate corresponding parts in the several iigures.

The object of this invention is to produce a harvesting-machine which will operate .in a more perfect and expeditious manner, and at the same time may he constructed at less cost than machines of this class as heretofore constructed. Y

My invention consists, first, in a peculiar arrangement ot' devices for imparting motion to thecutterbar; second, in adevice for preventing injury to the grain, all as will be hereinafter fully explained.

In order that others skilled in the art to which my invention appertains maybe enabled to fully understand and use the same, I will proceed to describe its construction and operation.

In the accompanying drawings, A B may represent the shoes, and C D E F G the lingers or guards, which latter are mounted upon a rod, H, which is inserted and securely fastened into the shoe A at one end, passes through the tingers or guards and through the shoe B, and is adapted to retain all securely together by means of a key, I, or other vsuitable locking device. Near their rear ends these fingers or guards are each formed with a pin, c, which pins project from the sides of said lingers and enter corresponding apertures in the sides of the adjacent fingers, so as to prevent any vertical-movement or displacement of the several fingers, the pins of the end fingers, U and G, taking into corresponding apertures in the shoes A B, and thus securing the entire series.

From the above description it will he seen that the fingers or guards, constructed and arranged as shown, and secured together in the mannerdescribed,constitute a substantial and durable finger-beam.

N represents a shaft, to which motion may be imparted by a gear-connection with the carrying-wheels of the machine, said shaft being journaled in .any suitable bearing. Upon one end of this shaft is loosely secured a crankwheel, O, which is caused to revolve by means of a pin, S, ou the shaft N, which comes in contact with a projection, T, on the wheel O.

The crank-wheel O is adapted to revolve inv for the purpose to tearing or injuring thestanding grain.

Operation: By my improved devices for impartiu g motion to the cutter-bar the same receives a much longer stroke than that given the cutter-bar ot' harvestingmachines as hith erto constructed. This difterence in the extent of the stroke given the cutter-bar by my improved method as compared with that received by the cutter-barof other harvesti11g-machinesl may be illustrated as follows: The cutter-bar W occupying a position in which the knife V is at the center of the nger O, it will be supposed that'the cutter is advanced from this point to its utmost extremityin the direction ot the shoe B. This stroke carries the said knife V t'o the center of the nger Gr. each knife working through four cutting-spaces, whereas by the mechanism commonly employed to reciprocate the cutter-bar-tlie knife Vwould only be moved to the center of the linger E. This arrangementadapts the cutter-bar to be moved with the requisite rapidity without the employment of multiplying gears, and also adapts the cutter-bar to be operated by less power.

The wheel O, being loosely journaled upon the shaft N, isadapted by its momentum to revolve with increased velocity at certain stages in the reciprocation of the cutter at 4which the same would otherwise move tardily or slowly, and thereby maintain a uniform regular motion. n

The manner described of forming the lin gerboard-that is to say, so that the lingers themselves will constitute the beam and guards for the cutter-bar--provides means for the substitution of fingers for any that may have become deranged or broken. This may be done by merely withdrawing lhe key I, which allows the shoe B to be removed. Any or all of the lingers may then be slid off the rod H and replaced with great facility.

The shoesA B, and more especially the latl(er, need not be of greater width than thosecommonly in use, the spring L preventing iniury to the grain by the knives on the end of the cutter in the manner already explained.

Having thus described my invention, what 1 claim as new therein,` and desire to secure by Letters Patent, is

1. The pin or projection S in the shaft N, in combination with the pin or projection T in the wheel O, for the purpose specified. 'i

2. The spring-guard L for the purpose ol protecting the standing grain or other material outside of the shoe B from the knife V and those following, as described and specied.
